Understanding notifications

Use alerts,
notifications, and groups to inform unique sets of users about only those issues important to
them, using an appropriate channel.

Using alert groups and notifications enables you to create groups of alerts and set up
notification targets for each group in such a way that you can notify different parties
interested in certain sets of alerts by using different methods. For example, you might
want your Hadoop Operations team to receive all alerts by email, regardless of status,
while at the same time you want your System Administration team to receive only RPC- and
CPU-related alerts that are in Critical state, and only by simple network management
protocol (SNMP).

To achieve these different results, you can have one alert notification that manages email
for all alert groups for all severity levels, and a different alert notification group that
manages SNMP on critical-severity alerts for an alert group that contains the RPC and CPU
alerts.
